Overview
Not a slim backpacking mummy, the Redwood is an oversized rectangular bag with a canvas shell and flannel lining built for extreme cold. Two offset layers of synthetic insulation block cold spots.
Room to move and a very low rating make it a cozy base camp bag in deep winter. Canvas and cotton add weight and bulk, and the listing gives no weight or packed size.
Who it's for
Deer camps, cabin trips and winter tent camping near the vehicle suit this bag. Hikers and anyone short on pack space should choose a compressible down or synthetic mummy.
Pros and cons
- Very low temperature rating
- Roomy rectangular cut
- Soft flannel lining
- Durable canvas shell
- Weight not listed
- Bulky to pack
- Cotton slow to dry if wet
- No stuff sack listed
Performance notes
Offset insulation layers cover each other's stitch lines, so there are no thin seams for cold to pass through. A rectangle has more air space to heat than a mummy. Canvas resists abrasion but holds moisture.
